Useful answers
Questions about webp compressor
Is WebP better than JPEG?+
WebP often produces smaller files at a similar visual quality and can also preserve transparency. JPEG remains useful for maximum compatibility.
Can I batch compress WebP?+
Yes. Add multiple files, apply one preset, then download every result as a ZIP.
Is processing private?+
Yes. CompressMint processes images locally in your browser. Your photos are not uploaded to our servers, and refreshing the page clears the working session.
